416 Taylor Info and Advice

Okay, so it's UPDATE TIME!

Little good news, little confusing news. First off, I managed to win an absolutely killer gunbroker auction last week. Or week and a half ago. It's been a busy time here. But the package came in Thursday and I finally got a chance between work stuff today to actually mess with it. What was in the package you ask? How about

1x RCBS 375 H&H trim Die
1x RCBS 338 Win Die set
1x RCBS 458 Win Mag Die Set
1x RCBS 240 Weatherby Die set
1x Lee 458 Win Mag Die set
1x Hornady 300 H&H Die Set
1x Hornady 458 Win Mag Die set
Oh And HOW ABOUT 1X LEE 416 TAYLOR DIE SET PLUS 17 PIECES OF QUAL CART BRASS!!

All of that came for $160 shipped. Considering the Lee dies and the brass are made of unobtanium infused with unicorn blood and forged in the fires of Mount Doom itself, I was prepared to go much higher. After the recent Amazon "buy 416 taylor dies that turned out to be 6.5x300 WBY" fiasco I was ready to drop coin especially after the pictures showed the die markings.

Before I had a chance to actually play with the new dies and such, I did manage to clean, pack and ship the Hornady dies over to @CZDiesel as a thank you for hooking me up with the 404 Jeffery ammo I needed on that project. First things first after all.

So today I got a chance to play. First up --- 6 of the pieces of brass were primed, so what better opportunity to de-prime them than using the Lee die. Sure the Redding one I have was preset, but I wanted this staged too. So I took it apart, cleaned it, wire brushed the threads, etc. Got it setup and wouldn't you know it worked great.

So we come to the real part of the test. Because I already had a die, and a 416 Ruger die I could use to seat the bullet, the real need was for a dedicated Taylor die that could crimp. So I queued up that die, cleaned it and set it. Now, to make things interesting, I'm doing my dummy rounds using a 410gr Woodleigh --- mainly because when I started this project I had those and no other bullets. So this one has become my test dummy. It happens to be somewhat on the larger side compared to the other choices now in stock here, but it is what it is.

But that does bring me to the first thing with the Lee die. I put it in, and did the setup routine:
1. Screw die in until touching the brass, back out a turn.
2. Seat the bullet to the groove, back out the seating stem.
3. Screw die in until it had a nice crimp
4. Put seating stem back in.

So Step 4 is where the process kind of broke down --- With the die configured for the right amount of crimp, the case/bullet were so far into the die that to set the bullet right would require the seating stem to be unscrewed. So this was a minor problem.

I solved it by going back to the well. I pulled everything, resized, and then used the 416 Ruger seating die to actually seat the bullet. Then, with the seating stem out, ran it through the Lee 416 Taylor die to apply the crimp. Extra step, but afterwards, I took the dummy round and ran it in and out of the chamber 6 times and the bullet didn't budge. That was the problem in earlier rounds --- after sizing and seating the bullet would be fine, but after 2x in/out of the chamber it'd just kind of fall apart.

So with this setup, I appear to have positive neck tension, a good crimp, and a bullet that doesn't move when being worked, and one that I anticipate wouldn't budge under recoil either. So all in all this appears to be a win. Once I get some test rounds made up and out to the range, I'll probably still order a custom crimp die though. I do anticipate that were I loading something like a 350gr Speer HotCor then the Lee die would work as an all in one. But for the Woodleigh and even the Hornady 400gr that I have the bullets are just too long.
 
Lee never came around to introducing the set screw locking nut. You have to buy RCBS or redding for that. All else is inferior junk that requires replacement with Superior parts!

That's true. I already stripped the Lee set's "locking" nuts off and added some nice one that I had waiting for it. :D
 
The lock nuts are cheap but kind of an unnecessary headache and waste of time! The only Lee I own are for 22 250.
 
Well, looking into this more I may have done made a boo boo on the 416 Rem brass. I apparently should have bought the 458. Dang it.

At least I know of someone selling a No 1 in 416 Rem mag soon, so maybe I have an excuse for it.
Yes the 416 REM is full size the 416 Taylor are standard size you can use 458win mag brass
 
Just got Norma brass from Raven Rocks. thank you sir!
Measured dimensions and case capacity to see how it matched up to the Manson reamer.
Case capacity was 93.3gns, case weight 209.4gns. Not sure who came first "the chicken or the egg":),
but they are a match. The reamer allows for a bit longer case length.
I should note that Redding confirmed their die is cut for the Manson reamer.

Saw a “Sammi” reamer print that matches Asquare drawing with the longer neck, shorter body and 25 deg shoulder. So I guess the Manson reamer is the “improved” version?

I would have thought all the .416 Taylor reamers and die sets would be the same dimensions for some time now since it was SAAMI speced decades ago? Guess not.
 
Me too! But the engineer in me makes me go down the rabbit hole…
The good news is that, bless their hearts, Manson, Norma, and Redding, took the time to match each other.
And dear Raven Rocks has a goodly supply of brass.

Hey Guys
when loading the 415 Taylor it seems like a lot of the pics I see of loaded ammo, it appears the projectiles are seated very long or extended out side of the case, is it dependent on the powder charge lets say 73 or 74gn of varget? im in the proses of building a Taylor and I didn't realize this until I started looking at the ammo

Sorry ment 416 Taylor
 
i am also building a 416 Taylor and for my load analysis, i used both h4895 and varget.
load density (around 100%), burn rate are almost the same, giving 2250fps and 65 gns.
using Hornady DGX 400gn and Woodleigh 410gn (meant for the Rigby). Measured Norma case capacity and bullets lengths. The DGX OAL is 3.145" and Woodleigh is 3.30" (seated to the top of the cannelure).
Lots of folks are using copper bullets and these are longer and to get the fps, seat out for a bit more case capacity.
I think the Woodleigh is just about the right bullet, uses all the magazine length (my will be in a CZ550 medium action), a bit ore weight and a hair more case capacity.

Interesting
The Woodleigh projectiles are not available at the moment and I was planning on using Barnes, hammer and possibly Northfork bullets as they seem to be one of the few available.
 
here are bullet lengths:
400gn hyd dgx- 1.382"
410gn wdl sn - 1.334"
400gn nf sp - 1.475"
400gn bar tsx - 1.590"

Hence my choice of either hyd or the wld in a std length action. If magnum action, then the copper works seated out.
Mine is a standard action so it can’t be seated out to much
 
I have one with a 22" bbl. With proper handloading, it's quite easy to get 2,450 fps (400 gr Swift/Barnes Banded Solids) and in testing 'developed a load that was closer to 2,550 fps. I think 2,350 is definitely more of a pleasure to shoot in most guns, but stuck with the 2,450 (all superbly accurate) and decided the >2,500 fps was unnecessary all the way 'round (and your shoulder will thank you!!!) Woodleighs used to be great in any form of 458 cases, not just because of terminal performance, but because they're the shortest bullets out there and allow a tad more powder space. I performed a LOT of testing (including many other recipes,) but this is what worked best. Again, the dual base powder load is overkill and Kevin Robertson's wisdom reminded me of same. Off the top of my head, the Swift (shorter) printed 1" higher than the Solid, so that worked out well for longer, non-DG shots on trophy PG. The gun was dialed in with the Solid zeroed at 100 and the Soft was precisely 1" high from it. With such a big bore diameter and expected modest velocities, you're not going to see much V deviation for 1-in less bbl. Smaller bores and >3,000 pfs Vs can easily see -100 fps/in or more (the reason most hot 257s and down have/need 26" bbls). As I recall the 2750 fps 06 is like -30 fps/in. You might be looking at 10 fps. There's a great old writeup regarding Robert Chatfield-Taylor's creation (it's a republished old magazine article in a Wildcatter's handbook,) but it's available online....Better powders/components exist today! Enjoy. Mine (SS M70/Shaw BBL/HS Precision w/ Hg Reducers/etc.) was inspired by my Son living in AK, so it's prepared for "dual-duty" of hunting big things.

Are you pleased with the performance of the ER Shaw barrel?
Their availability seems to be a little bit better.
Did Shaw install your barrel, or delivered short chambered and threaded for a gunsmith?

I need to know if this is legit. Photo with today's paper would do it.

Thanks
